If I'd sell the hardware I'd get better RAM, alot better CPU, for about 200€ after selling my old hardware and buying the new one, now the question is... Will it be worth it? +rep to all. Considering my "skills" I could get my SB to 5Ghz unless I'm REALLY unlucky. thanks!

Wut skills? No offense but 90% of overclocking is luck of the hardware . Overclocking isn't exactly rocket science ha, and Sandy Bridge simplifies it even further.

If you can sell your current setup for all of your costs, IMO there is no reason not to upgrade.

Dude, I wanna see some screenshots of you pumping 1.45 volts into your CPU and not going over 75C in a prime95 small FFT run, I did 1.38 on my megahalems with a kaze3000 at max speed with the window open and I hit 80 in seconds lol. Unless your ambient is like 10C.
